Blackpool chairman Karl Oyston has said any "conspiracy theories" about a fall-out between himself and Michael Appleton are untrue and not the reason for Appleton's departure to Blackburn.
Appleton's 65-day reign at Bloomfield Road ended on Friday when the 37-year-old was
Oyston told BBC Radio Lancashire: "People always default to conspiracy theories and perpetuate rumours.
"There's no fall-out. That's one of the more easily dismissible rumours going."
He added: "We should dismiss it because it's factually incorrect."

"Fans follow football throughout the world and anyone who's shocked by this is very naive, frankly.
"It's not unheard of in football that people get better offers and move on. It's part of the very nature of the sport that we all follow."
Oyston and Blackpool are now faced with searching for another new boss, just two months after Appleton was brought in to replace Ian Holloway, who left to join Crystal Palace at the start of November 2012.
